 <div class="block">Validates the parse tree of a SQL statement, and provides semantic
  information about the parse tree.

  <p>To create an instance of the default validator implementation, call
  <a href="SqlValidatorUtil.html#newValidator(org.apache.calcite.sql.SqlOperatorTable,org.apache.calcite.sql.validate.SqlValidatorCatalogReader,org.apache.calcite.rel.type.RelDataTypeFactory,org.apache.calcite.sql.validate.SqlValidator.Config)"><code>SqlValidatorUtil.newValidator(org.apache.calcite.sql.SqlOperatorTable, org.apache.calcite.sql.validate.SqlValidatorCatalogReader, org.apache.calcite.rel.type.RelDataTypeFactory, org.apache.calcite.sql.validate.SqlValidator.Config)</code></a>.

  <h2>Visitor pattern</h2>

  <p>The validator interface is an instance of the
  <a href="../../util/Glossary.html#VISITOR_PATTERN"><code>visitor pattern</code></a>.
  Implementations
  of the <a href="../SqlNode.html#validate(org.apache.calcite.sql.validate.SqlValidator,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>SqlNode.validate(org.apache.calcite.sql.validate.SqlValidator, org.apache.calcite.sql.validate.SqlValidatorScope)</code></a> method call the <code>validateXxx</code>
  method appropriate to the kind of node:
  <ul>
  <li><a href="../SqlLiteral.html#validate(org.apache.calcite.sql.validate.SqlValidator,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>SqlLiteral.validate(SqlValidator, SqlValidatorScope)</code></a>
      calls
      <a href="#validateLiteral(org.apache.calcite.sql.SqlLiteral)"><code>validateLiteral(org.apache.calcite.sql.SqlLiteral)</code></a>;
  <li><a href="../SqlCall.html#validate(org.apache.calcite.sql.validate.SqlValidator,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>SqlCall.validate(SqlValidator, SqlValidatorScope)</code></a>
      calls
      <a href="#validateCall(org.apache.calcite.sql.SqlCall,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>validateCall(SqlCall, SqlValidatorScope)</code></a>;
  <li>and so forth.</ul>

  <p>The <a href="../SqlNode.html#validateExpr(org.apache.calcite.sql.validate.SqlValidator,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>SqlNode.validateExpr(SqlValidator, SqlValidatorScope)</code></a> method
  is as <a href="../SqlNode.html#validate(org.apache.calcite.sql.validate.SqlValidator,org.apache.calcite.sql.validate.SqlValidatorScope)"><code>SqlNode.validate(SqlValidator, SqlValidatorScope)</code></a> but is called
  when the node is known to be a scalar expression.

  <h2>Scopes and namespaces</h2>

  <p>In order to resolve names to objects, the validator builds a map of the
  structure of the query. This map consists of two types of objects. A
  <a href="SqlValidatorScope.html" title="interface in org.apache.calcite.sql.validate"><code>SqlValidatorScope</code></a> describes the tables and columns accessible at a
  particular point in the query; and a <a href="SqlValidatorNamespace.html" title="interface in org.apache.calcite.sql.validate"><code>SqlValidatorNamespace</code></a> is a
  description of a data source used in a query.

  <p>There are different kinds of namespace for different parts of the query.
  for example <a href="IdentifierNamespace.html" title="class in org.apache.calcite.sql.validate"><code>IdentifierNamespace</code></a> for table names,
  <a href="SelectNamespace.html" title="class in org.apache.calcite.sql.validate"><code>SelectNamespace</code></a> for SELECT queries,
  <a href="SetopNamespace.html" title="class in org.apache.calcite.sql.validate"><code>SetopNamespace</code></a> for UNION, EXCEPT
  and INTERSECT. A validator is allowed to wrap namespaces in other objects
  which implement <a href="SqlValidatorNamespace.html" title="interface in org.apache.calcite.sql.validate"><code>SqlValidatorNamespace</code></a>, so don't try to cast your
  namespace or use <code>instanceof</code>; use
  <a href="SqlValidatorNamespace.html#unwrap(java.lang.Class)"><code>SqlValidatorNamespace.unwrap(Class)</code></a> and
  <a href="SqlValidatorNamespace.html#isWrapperFor(java.lang.Class)"><code>SqlValidatorNamespace.isWrapperFor(Class)</code></a> instead.</p>

  <p>The validator builds the map by making a quick scan over the query when
  the root <a href="../SqlNode.html" title="class in org.apache.calcite.sql"><code>SqlNode</code></a> is first provided. Thereafter, it supplies the
  correct scope or namespace object when it calls validation methods.</p>

  <p>The methods <a href="#getSelectScope(org.apache.calcite.sql.SqlSelect)"><code>getSelectScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="#getFromScope(org.apache.calcite.sql.SqlSelect)"><code>getFromScope(org.apache.calcite.sql.SqlSelect)</code></a>,
  <a href="#getWhereScope(org.apache.calcite.sql.SqlSelect)"><code>getWhereScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="#getGroupScope(org.apache.calcite.sql.SqlSelect)"><code>getGroupScope(org.apache.calcite.sql.SqlSelect)</code></a>, <a href="#getHavingScope(org.apache.calcite.sql.SqlSelect)"><code>getHavingScope(org.apache.calcite.sql.SqlSelect)</code></a>,
  <a href="#getOrderScope(org.apache.calcite.sql.SqlSelect)"><code>getOrderScope(org.apache.calcite.sql.SqlSelect)</code></a> and <a href="#getJoinScope(org.apache.calcite.sql.SqlNode)"><code>getJoinScope(org.apache.calcite.sql.SqlNode)</code></a> get the correct scope
  to resolve
  names in a particular clause of a SQL statement.</p></div>
